SASH-HOLDER.

SPECIFICATION forming part of Letters Patent No. 557,803, dated April 7,1896.

Application filed August 29,1895. Serial No, 560,888. (No model.)

To (LZZ 10 7007771 it mcy concern:

Be it known that I, CHARLES HADDEN, a citizen of the United States,residing at Mazon, in the County of Grundy and State of Illinois, haveinvented certain new and useful Improvements in lYindows and YVindow-Frames; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in windowsand windowframes, and more particularly to means for raising andlowering the sash and holding it in any desired position.

It has for its object, among others, to provide a simple and cheapconstruction which will permit of easy movement of the window and whichwill not be aected to any material extent by the changes in theatmosphere, working as well in damp weather as in dry. It embodiesguides upon the inner faces of the window-iframe, in which travelrollers which have a bearing against spring-pressed plates seated invertically-disposed grooves in the outer faces of the sash. The springspress with sufficient force against the strips to hold the sash againstmovement at any desired point. Means are provided for ready detachmentof the sash when necessary.

Other objects and advantages of the invention will hereinafter appear,and the novel features thereof will be particularly pointed out in theappended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thisspecification, and in which- Figure l is a perspective view of a frameand sash, showing myinvention, a portion be ing broken away to betterdisclose other features. Fig. 2 is a vertical section through the same.

Like letters of reference indicate like parts throughout both views.

Referring now to the details of the drawin gs by letter, A designates awindow-frame, upon the inner faces of the side rails of which are theguide-strips B, which form a bearing for the strips C, as well as atrack for the rollers D. These strips are arranged in grooves E, formedin the outer faces of the side rails of the sash F, and these plates orstrips are urged outward by the springs G,

located in said grooves and bearing against the inner faces of thestrips or plates. The rollers may be of any suitable Construction andmay be more or less in number, as may be required. They may be insertedin position in any suitable way, and in Fig. 1 I have shown one of theguide rails or strips as provided with openings I, through which therollers may be passed.

The sash may be retained against displacement in any suitable manner. InFig. 1 I have shown the blocks K secured to the side bars of the frameand serving to prevent displacement of the sash, and if desired otherblocks, L, may be provided near the lower end of the frame, as I havealso shown in Fig. 1.

lVith the parts constructed and arranged substantially as above setforth the operation will be apparent. The window is raised and loweredin the usual manner, and the rollers bearing against the strips orplates tends to reduce the friction, rendering the window easilyoperated, while the springs urging the plates or strips outward againstsaid rollers forms sufficent friction to hold the sash in any of itsadjusted positions. The rollers and the springs will be of a size andcharacter depending upon that of the sash in connection with which theyare employed.

Modifications in detail may be resorted to without departing from thespirit of the invention or sacrificing any of its advantages.

hat is claimed as new is- 1. The combination with the window-iframe andits guides, of a sash provided with springpressed strips, and rollersworking in said guides and engaged by said strips, substantially asdescribed.

2. The combination with the window-frame and its guide-strips, havingopenings for the insertion of rollers, of the sash having grooves in itsside rails, springs located in said grooves, strips in said groovesbearing against said springs, and rollers between the guides of theframe and against which said strips bear, substantially as and for thepurpose specified.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

CHARLES HADDEN.
